: My wife recently recovered from pneumonia (or so we thought) enough to try returning to work. However, after a couple of days, she was having trouble breathing and felt like her legs were going to collapse.: Her doctor eventually sent her to emergency where tests were conducted with the result that she was told she has "Low blood oxygen levels": Does anyone know the meaning or implication of this ? i.e. what causes it, can it be treated,is it permanent etc..: Any help much appreciated. Thanks

Check with your doctor. He Should have explained it to your satisfaction...If you don't understand the problem and the solutions you can't help in your own recovery and or treatment. Don't ever walk out of a physicians office or let them leave a bedside unless YOU UNDERSTAND the problem...Check with your doctor again but it means that the lungs are not functioning the way they should. The lungs supply O2 to the blood which distributes it to all the cells in the body. Suplemental O2 is sometimes used. That's what they put me on when I had that condition. The underlying cause was a bad pulmonary infection. You have to find out the reason for the lung disfunction. Talk to your doctor again..
